成像过程中,被摄像目标与摄像机之间的相向运动会造成图像的辐射状模糊。根据相向运动成像特点给出了仿视网膜探测器像元布局的初始结构,建立了其在相向运动成像过程中的成像仿真模型。由仿真实验结果建立了探测器结构参数、模糊度及成像质量三者的关系,验证了仿视网膜探测器在高速相向运动成像中的优势,为仿视网膜探测器的设计奠定了基础。 During the imaging process, the opposite motion between the camera target and the camera will cause the image to be radiated and blurred. According to the characteristics of the relative motion imaging, the initial structure of the retinal retinal detector cell layout is given, and the imaging simulation model of the retina probe is established. The relationship between the structural parameters, the degree of ambiguity and the imaging quality of the detector is established by the simulation results. The advantages of the simulated retinal probe in high-speed phase-contrast imaging are verified, which lays the foundation for imitating the design of retina probe.
